What Are Whitman Controls and Why Do They Matter?
Whitman Controls focuses on manufacturing small switches and sensors to measure pressure, vacuum, temperature, and liquid level. These devices may be small in size, but they are the starter motors for your smart building.
If you think of a building as a living organism, then Whitman Controls is your nervous system. They monitor what’s going on and deliver information throughout the building. Have you noticed any temperature issues? There was no need to call the air conditioning system, as Whitman Controls had already told it to kick on because it was too hot. Similarly, whenever the water level becomes too high, they simply know when to tell the safety system to kick on as needed!
In May of 2024, Whitman Controls demonstrated its growth and commitment to investing in its future growth strategy by announcing a $4.5 million investment strategy to accelerate growth!
How Whitman Controls Work in Buildings
Whitman Controls works by monitoring conditions in real-time. They use sensors to check:
- Air pressure in HVAC systems
- Temperature in different rooms
- Water levels in tanks and pipes
- Vacuum levels in specialized equipment
When conditions change, the controls send signals to other systems. This happens automatically, without human input. The result is buildings that respond quickly to changing conditions.
Top Whitman Controls Providers
1. Capitol Area Technology
Capitol Area Technology (CAT), located in Texas, is focused on spare parts for semiconductors and manufacturing. Originally, they were a prominent 3rd party source for a mix of new, used, and refurbished parts and worked with many well-known tech companies. Although their focus is mostly on broader high-tech companies, they have Whitman Controls products featured. As a parts supplier, they satisfy many other requirements as well.
Features
As a supplier of Whitman products, they have Whitman switches, for example, the W117G-3H-F12TB (snap switch) and P119G-3N-K52L-X (pressure switch). These were designed for clean high-purity applications, with the parts made from stainless steel in order to be resistant to leaking. CAT has an online store where you can see stock status for quick orders and delivery, and even offer repairs.
Benefits
Using certified CAT’s refurbished equipment means less downtime waiting for parts in critical supply chains, like making chips; even a minor itinerary delay can cost me major dollars. They can safely provide cost savings of up to 50% of the cost for refurbished versus only new equipment, without losing an ounce of quality. For small business owners, this helps with stretching budgets. Plus, their team located in the U.S. can provide the support I need quickly, minimizing the minimization of risk in fast-moving industries.
How It Works
Consider this use case: your semiconductor line has a pressure switch that is failing. You find a replacement Whitman on CAT’s site and order it. They ship from Texas and have same-day shipping in some circumstances. They can also repair your old one if needed. This provides seamless continuity of operations with this solution aligned to tech-efficient and sustainable practices, which are key for reusing equipment for cost savings and less diversion to waste.
The possibilities from CAT’s model align with the 2025 push for a more efficient supply chain in capability areas, especially with the market growing with increased use of AI for factories.
